Int 61 Fn 000F  - Banyan Vines - Vines Socket Api (far Data)               [N]

   AX = 000Fh
   CX:BX -> request block (see #3115)
   DX = application's data segment (should be = CX)
   ES = DS

Return: AX = status
       0000h successful
       0099h invalid operation
       00A5h resource not available
Desc:  StreetTalk access with session handles

Notes: This service is handled by the adapter driver
   The request dispatch table contains dummy entries for subfunctions
     06h, 0Dh, 0Eh, 0Fh, 10h, and 11h, which always return error 0099h
     (invalid operation) in the request block's result buffer
   This interface does the same as the corresponding AX=0001h interface,
     but with a slightly modified request block structure (i.e it allows
     FAR parameter block pointers) and without expecting DS=0001h
   Some adapter drivers (e.g. the NDIS2 token ring driver NDTOKBAN for
     VINES 5.53) ignore the value in CX and use the value from DX instead
